  • Patent number: 11284887
    Abstract: An assembly used in osteosynthesis comprising a delivery instrument in combination with an implant wherein the delivery instrument releasably holds the implant in a first configuration prior to attachment of the implant to bone. The delivery instrument allows the implant to be affixed to bone before the implant is released from the instrument. And the instrument may comprise guide means for drills, depth gauges, screws, pins, pegs, blades and or drivers which are used or implanted when the implant is releasably attached to the instrument. After the implant is affixed to bone and released from the delivery instrument, the implant assumes at least a second configuration which provides compression and or distraction and or control of spatial orientation.

  • Patent number: 11284886
    Abstract: A system for implant delivery includes an implant and an inserter. The implant includes a body that extends between first and second ends. The implant includes retainers extending outwardly from the first and second ends. The retainers are received in corresponding jaws of the inserter. When the implant is connected to the inserter and the inserter is actuated, the implant elastically deforms.

  • Publication number: 20220079578
    Abstract: A bone plate system may include a bone plate having a bone-facing side, an obverse side displaced from the bone-facing side by a thickness of the bone plate, a first end, and second end displaced from the first end along a longitudinal length of the bone plate. The bone plate may have a first fastener hole extending through the bone plate between the bone-facing side and the obverse side, a second fastener hole extending through the bone plate between the bone-facing side and the obverse side, and a plug extending outwardly from the bone-facing side. The plug may have a cross-sectional shape, perpendicular to the thickness, that is elongated along the longitudinal length.

  • Publication number: 20220061855
    Abstract: A surgical saw blade is disclosed for improved resection and cutting of tissue. The surgical saw blade may include a front side, an opposite back side, a top side, an opposite bottom side, a right side, and an opposite left side. The surgical saw blade may further include a cutting tooth extending from the back side and having a cutting edge oriented toward one of the right side and the left side, the cutting tooth associated with an aperture through the saw blade between the front and back sides. The back side may be a single direction cutting side and the front, top, bottom, right, and left sides may be non-cutting sides. The surgical saw blade may further include a saw connection feature near the bottom side.

  • Publication number: 20220031371
    Abstract: A bone plate assembly may include a bone plate with an obverse side, a reverse side, a fastener hole formed through the bone plate from the obverse side to the reverse side, a first draw hole formed through the bone plate from the obverse side to the reverse side, with a wire engagement surface, a fastener insertable through the fastener hole and into tissue, and a first wire insertable into the first draw hole, with a distal end anchorable in the tissue and a proximal end with a retention portion that is retainable in the first draw hole. The wire engagement surface may be oriented obliquely relative to a pilot hole formed in the tissue to receive the wire such that motion of the first wire through the first draw hole exerts a compressive force against the tissue.

  • Publication number: 20220000470
    Abstract: A knotless suture anchor system is disclosed for improved anchoring in tissue. The knotless suture anchor system includes an anchor body having an exterior surface, a proximal end, a distal end, a longitudinal axis extending between the proximal and distal ends, an interior longitudinal passageway extending at least partway from the proximal end toward the distal end, a proximal opening communicating with the longitudinal passageway nearer the proximal end, and a distal opening communicating with the longitudinal passageway nearer the distal end. The knotless suture anchor system also includes an interference member insertable distally into the longitudinal passageway to secure a portion of a suture within the longitudinal passageway by compressing the portion of the suture between the interference member and the anchor body, and a frangible connection that joins a proximal member to the anchor body.

  • Publication number: 20210394944
    Abstract: A terminally sterilized medical procedure kit includes a recovered item and a new item packaged together as a single stock keeping unit. A method for processing at least a portion of a first medical procedure kit includes the steps of receiving a recoverable item of the first kit, performing a processing operation on the recoverable item, providing a new item, combining the recoverable item and the new item in a second kit, and terminally sterilizing the second kit. A method for recovering at least a portion of a terminally sterilized medical procedure kit includes the steps of purchasing a recoverable item of the first kit from an owner and receiving the recoverable item by the purchaser.
